When I brew according to the instructions by the picobrew in my pico C the resulting beer has way too much yeast flavor. I already had 3 batches and all of them have this problem.
Edit: After getting more details I noticed their manual changed.
Here is old version of the manual (the one I actually followed for my brews): https://drive.google.com/file/d/0B8oEUsdj4NpSWFdvYjIyODY0bUE/view?usp=sharing
Here is new one: https://picobrew.com/About/Manual_PicoC.cshtml
Fermentation step actually now is different. (page 60 step 2)
I guess I should try with new instructions and see if it's any better (they do say to pitch only half of packet now, instead of full. Also they no longer recommend to aerate the wort).
My original question was: How to minimize the yeast flavor?
I tried tasting beer 1 month after bottling, 2 months, 3 months. It's always way too much yeast flavor.
